Reply: nbecker_at_[hidden]: "Re: [boost] CRC-64, please forward" 

I have attached a couple of source files. Would somebody be so 
kind as to forward them to whoever it is that maintains the Boost 
CRC component? They implement a 64-bit CRC, which when last I 
checked Boost didn't have yet. This is the CRC used in modern 
tape drives, as extracted from PostgreSQL and C++ified. 


I apologize for imposing on the group by not looking up the 
responsible party myself, or composing the code appropriately 
for inclusion; this is all I have time for at the moment, and 
I thought it might be more useful to have it now, as-is, than 
to wait until someday when I have more time.
